Forcing NTP to update?

I am using NTP on my AS5200 and 3640's, but it isn't synching. Is there a way to force it to synch? Some of my routers are synching and some aren't. I have my routers set up w. the NTP server x.x.x.x pointing back to the main NTP server router. Do I need anything else?

Re: Forcing NTP to update?

You may need to set the system time on the router manually then apply NTP. NTP does not sync up properly if it is off by more than a certain amount of time. I do not remember the exact limit, but I know its more than 5 minutes. Also, have you checked that the NTP server has a route back to your router that is not syncing, and vice-versa?

Try debug ntp packet and see what's going on!
